Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information
Brief Summary:
To assess investigator engagement of μCor system data in the context of heart failure management. The μCor system includes a sensor and wearable patch for fluid management.

Condition or disease Intervention/treatment Phase
Heart Failure Device: μCor Not Applicable

Detailed Description:

Subjects meeting the inclusion/exclusion criteria will wear the μCor for up to 90 days.

During the study, face to face follow up will occur every 30 days. For all subjects, each scheduled clinic visit will include assessment of cardiac signs, symptoms, and any relevant clinically actionable events.

The subject will be given a daily diary to track symptoms, hospital visits, medication changes, and all other heart failure related clinical events.

Weekly phone calls to the subject will be given throughout the duration of the study to remind the patient to use the subject diary and to collect and record heart failure related clinical events.

The subject's health care provider team will receive the μCor data through access to a clinical tool interface. The clinical tool will send data updates that are dependent on the μCor data trends. The data updates will allow the health care provider team to take action when the data indicate worsening heart failure, within the context of standard of care medical practice and patient specific parameters. Weekly data reports will be delivered to the investigators.

Subjects will be contacted six months and one year from initial enrollment to assess the vital status of the subject, any heart failure related clinical events since the end of μCor wear, and any health care utilization since the end of μCor wear.

Arm Intervention/treatment
Experimental: Device Data Engagement Assessment
This arm will assess the endpoints of investigator engagement with the device data.
 Device: μCor
μCor consists of the following components: A) Patch B) Sensor C) Charger D) Data transmission device (Gateway) E) Server Once activated, the wearable Sensor automatically acquires ECG, RF readings, heart rate, respiration rate, activity, and posture measurements.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Investigator Engagement of Device Data [ Time Frame: Through study completion, an average of 2.5 years. ]
    Quantification of investigator actions after viewing device data.


Secondary Outcome Measures :
  1. Correlations of the μCor measured thoracic fluid index to heart failure related clinical events. [ Time Frame: 90 days. ]
    Reading: thoracic impedance index (relative value that is normalized to a baseline radar impedance). Clinical heart failure events will be collected in the Case Report Forms.

  2. Correlations of cardiac rhythm μCor measurements to heart failure related clinical events. [ Time Frame: 90 days ]
    Reading: cardiac rhythm measured as heart rate (beats per minute)Clinical heart failure events will be collected in the Case Report Forms.

  3. Correlations of respiration rate μCor measurements to heart failure related clinical events. [ Time Frame: 90 days ]
    Reading: respiration rateClinical heart failure events will be collected in the Case Report Forms.

  4. Correlations of the μCor measured thoracic fluid index and heart failure related symptoms. [ Time Frame: 90 days ]
    Reading: thoracic impedance index (relative value that is normalized to a baseline radar impedance).Heart Failure symptoms assessed through subject reported symptoms captured in the Case Report Forms.

  5. Correlations of cardiac rhythm μCor measurements and heart failure related symptoms. [ Time Frame: 90 days. ]
